TBH, this doesn't make any sense, you can buy both cilantro and coriander for cooking. They're both regular ingredients, so they're both culinary terms.
Normally cilantro is the leafy part and coriander is the seeds (you can get whole or crushed).
That's at least true for American English. I'm unclear if it holds true in British, Australian, etc. Or if it works in other languages that use these words.
Never got a soapy taste from cilantro, but as a kid, a suicidal stink bug landed on a PB&J I was eating.
At first I was pissed off at my brother, cuz that bastard put cilantro on a fucking PB&J!!! I spit the bite out. Wad of partially chewed sandwich, mixed with insect legs and broken shell lands on my plate: no cilantro. Brother is now looking up at me with a genuine expression of concern: not a prank.
Lesson 1: look before you bite.
Lesson 2: Stink bugs taste exactly like cilantro.
Lesson 3: ...cilantro tastes exactly like stink bugs.
The tiniest little flek of that shit can ruin an otherwise delicious bite of food.
@Sterile_Technique@PunnyName in some dystopian future where cilantro has gone extinct, stinkbugs get crushed up and dyed green as fake cilantro powder, much like horseradish pretends to be wasabi...... What a dark place that must be
Oh yes I forgot about Indian. I have to be picky about where I go so I can avoid cilantro. Cooking does help a little bit the soap is still there for me. It's really overwhelming in dishes to me.
